Indiana University and Northwestern University Libraries Receive Mellon Grant for Avalon

Michael Friscia

Hydra community:

I’m pleased to be able to announce that the Indiana University Libraries, in partnership with Northwestern University Library, have received a $750,000 grant from the Andrew W. Mellon Foundation to support work on the Avalon Media System project through January 2017.

This funding will help to support the following activities: 1) developing additional features and functionality for Avalon to better meet needs of collection managers and users; 2) conducting studies of use of audio and video collections by researchers in humanities disciplines to help ensure future support for scholarly use; 3) integrating the Spotlight exhibit tool with Avalon to allow librarians, archivists, and scholars to showcase and provide additional context for media items and collections; 4) developing and implementing a community-funded business and governance model to sustain ongoing support and development for Avalon; and 5) deploying Avalon in a hosted software-as-a-service model for use by institutions that need the functionality of Avalon but would prefer to utilize a cloud-based software-as-a-service option rather than support a locally hosted instance.

I’d like to offer thanks to the Hydra community for building and maintaining a solid technical foundation that enables systems such as Avalon to be built and to members of the Hydra community who have assisted with Avalon’s development by providing feedback on requirements and implementation experiences.

More information is available in a press release from Indiana University at http://news.indiana.edu/releases/iu/2015/03/mellon-grants-digital-preservation.shtml

Best,
Jon

Indiana University and Northwestern University Release Avalon 3.3

Michael Friscia

Indiana University and Northwestern University are pleased to announce Avalon Media System 3.3. Release 3.3 adds the following capabilities:

  • MARC metadata Import
  • Ingestion of pre-transcoded derivatives with multiple quality levels
  • Script for recovering disk space taken up by temporary Matterhorn files
  • UI Improvements and Bug fixes

Users of Avalon 3.2 can take advantage of these new features by Upgrading Avalon 3.2 to Avalon 3.3.

For a more comprehensive list of changes, see the 3.3 release notes.

For more details on each of these new features, visit the What’s New in Avalon 3.3 wiki page: https://wiki.dlib.indiana.edu/display/VarVideo/What%27s+New+in+Avalon+3.3

Please feel free to try out Avalon 3.3 on our public test server (http://pawpaw.dlib.indiana.edu) before installation. Installation options include virtual machine image, manual installation, and source code installation. More information on all available options can be found on the Avalon web site’s Download page: http://www.avalonmediasystem.org/download

We welcome your feedback on Avalon 3.3 via the avalon-discuss-l discussion list. Join the discussion list at http://www.avalonmediasystem.org/connect

Best regards,

Indiana University Receives NEH Grant for Digital Preservation using Hydra

Michael Friscia

The National Endowment for the Humanities recently awarded the Indiana University Libraries and WGBH Boston a grant to support the development of HydraDAM2. This preservation-oriented digital asset management system for time-based media will improve upon WGBH’s existing HydraDAM system and work seamlessly with the Avalon Media System for user access, among other features.

Both HydraDAM and the Avalon Media System grew from the Hydra community. Hydra is an open source technology framework that supports the creation of preservation and access applications for digital assets based on the Fedora repository system. A community of institutions known as the Hydra Partners works together to maintain the framework and create applications for local or shared use by libraries, archives, and cultural institutions. Both Indiana University and WGBH Boston are among the 25 Hydra Partner institutions. Indiana University is collaborating with Northwestern University on the development of the Avalon Media System and WGBH developed the original HydraDAM system with help from the Data Curation Experts group.

HydraDam is based on the popular Hydra application Sufia. You can view some interesting examples of institutions using Sufia for digital preservation here:

Penn State: ScholarSphere

Notre Dame: CurateND

Case Western: Digital Case

Avalon Meeting Notes for Nov 24

Michael Friscia

We had a very productive meeting with three guests: Jon Dunn, Project Director, Indiana University; Mark Notess, Product Owner, Indiana University; Julie Rudder, Product Owner, Northwestern University.

The day started with an introduction to Avalon Media Systems in the Library Lecture Hall which included demonstrations of the work of Indiana and Northwestern who very recently released their first Avalon collections to the public. Powerpoint from the presentation is attached here: Yale Avalon Conference This lecture was video taped but sound is lacking, please contact michael.friscia@yale.edu for access.

Later in the day a smaller group convened to have a technical discussion about the future roadmap of Avalon. A recent poster that gives a very high level view can be seen here: RudderAvalon2. I am hoping to acquire a copy of the powerpoint presentation which has bullet lists of all the planned work that will go into version 3.2 through 4.0.

While we are still in the discussion stages of a project to bring Avalon up at Yale, two of the most important features for us include integration with Fedora 4 and possible integration of the backend transcoding processes into Sufia (Penn State has a version of Sufia called ScholarSphere). Our goal would be to integrate the two Hydra applications together so that audio and video files loaded into the self archiving product, Sufia, would take advantage of all the features of the Avalon Media System.

In addition, we discussed many topics including scaling Avalon so that it could transcode more than one file at a time, use RDF for describing complex relationships between multiple files/tracks and digital preservation.

 

 

Avalon Media Systems

Michael Friscia

Some preliminary work has been going on in the Digital Library Programming group to investigate Avalon for use in delivering audio and video content from our Hydra repository. Avalon is an open source software package that was developed by the Hydra partners: Indiana University and Northwestern University. We are considering adopting it for some of our audio/video needs as we consider ingesting audio and video into our Hydra repository.

In the video you will see an instance of Avalon that I have running on a virtual server on my computer. To access, I am using a web browser pointing to the virtual server, the URL only works from my computer. The only customization made to the software was to include a small Yale Library logo in the upper left, otherwise the software is “out of the box” and is bundled with an open source media streaming server. The content in this test instance is delivered as part of the “trial version” of the software so that you can see how it works without investing a lot of time.

The video is just under two minutes and demonstrates browsing to a video and showing playback. I demonstrate some of the basic playback controls including full screen. I then show how the video can be embedded on other web pages for sharing the content. Lastly I demonstrate the most basic type of content restriction where I set the requirement that you must be logged into Avalon in order to view the video. I then reload the web page that I embedded the video onto to demonstrate that I am now required to login. After logging in, the video begins to playback.

The video below is best viewed in full screen, it does not require sound but if you do have speaker or headphones, you will hear the music while the video is playing. (youtube link if the video below does not work)
